transverse tubes at the points of junction thereof with saldwaterlegs Branch pipes QQ are connected at, determinate intervals withsaid air supply pipes and extend downward therefroni between said archedtubes and terminate, w'ithin the fire. chamber below said pipes. These branches are preferably slightly curved upward attheir innervends.

The inner. ends ofthese lateral branches are providedtwith air distributivenozzles of any suitable form. In the; form shown theouter. end of each branch. pipe 20 is vprovided with-Fan internal sereivthreadQland with a multiplicity of lateral orifices 22 near the outer end of the branch and with i an: otherseries of lateral orificesv23 disposed around thebranchat .a greater distance.

a from the end thereof. An example, of a nozzle 20 in duplex form isshown in Fig-M1.

This duplex, n0zzle20 may be r usedeindependently or in connection with the single nozzles 20. This duplex nozzlei compr-isestwo laterally curved branches and when used between the singl nozzles 20 it delivers the air in; diverging'streams which 'commingle with thet streams of adjacent. nozzles andtends t0 spreadthe distributive air over thefire, A cylindrical pl-ugfioiis providedwith external screwthreads 26- fitting the screwthreads of the, branch tube. This plug is provided on' its periphery with a series of longitudinal channels 27 whichfltaper;

Insuch adjustment .the :triangular v-ishaped chan nels are exposedat theperipheriesf whereby a a slight movementmf the, plug,.will effect substantial changes in the delivery orifices.

For instance aunoutwardturning ,=of. the

plug 25 from the position shown ,in Fi'gqfi, where it is ,flush with. the..r:end .oflthe nozzle 20, will enlarge the orifioesaofsaid channels 7 which 'flareinWa-rd, such enlargement being proportionalstd the -.distance said plug is.

turned; outward-" Such, outward turning also, brings. the c deeper portions of said channels opposite the lateral orifices 22 and 23 and enables a larger volumeof air to pass out through said lateral orifices.

In the form of embodiment shown in Fig.

the air supply pipes'lO are disposed on opposite sides of the combustion chamber of the furnace below the lowermost series of arched transverse tubes but in contact therewith at their points of junction with said water legs and the branch pipes do thereof disposed at regular distances apart opposite the spaces between said arched tubes are slightly inclined upward, and the plugs 25 thereof are of the same construction as those of the branch pipes 20. The air supply pipes in both forms of embodiment are disposed at the lowermost series of transverse water tubes and the branch pipes or 40 aresubjected to the action of the currents of hot gases passing through the spaces between the water tubes and are in position to deliver the heated air through the nozzles to directly intermingle with said gases as soon as they leave/the coal.

The vair supply pipes 10 maybe provided with an injector 11 as shown in Fig. 3 of a construction like that illustrated in my Patent No. 1,106,?09, dated August 11, 191i.

In the use of this device, two tubes 10 are disposed within the combustion chamber on opposite sides of the walls thereof and the lateral branches 20 or $0 thereof project inward to points over the mass of burning coal, and deliver jets of heated air into said chamber along the whole length thereof. The air thus delivered is thoroughly mixed and commingled with the products of combustion and supplies xygen thereto, whereby said products are ignited and consumed.

The air distributers constituting this smoke consuming device may be hung over the arched water tubes and project down ward between them or be supported along the vertical tubes on Opposite sides of the chamber;

I claim asmy invention:

lsThe combination with a tire chamber provided with arched water tubes disposed apart from one another and having water legs on opposite sides of said chamber of a smolre consuming attachment comprising longitudinal air supply tubes resting on said arched tubes at opposite sides or said chamber, branch tubes at determinate intervals connected with said air supply tubes and extending downward between said arched tubes and provided with distributive nozzles projected into said chamber below said arched tubes.
